Hi, when I try to upgrade the software version on the AP the CNUT´s log table show
WARN Message: Upgrade unsuccessful. AP returns error code -9002. Rebooting device to prepare for the net upgrade attempt.
Then the unit reboot and I try to access but no response… at the same time my O.S. show warning about IP conflict but I don´t change my IP and the AP unit (deafult IP 192.168.2.101) any time.
Do you know about the error code -9002???
Thanks for your attention. Sorry for my English.
I had a similar issue, first try a different machine. If that doesn’t fix it, then I would contact support.
I know this is an ancient thread, but it’s the only search result on the forum for error -9002.
I just ran into this problem. Turns out I had mis-read the manual for upgrade procedure:
"Make sure that Passive FTP is disabled on the Update > Configure menu before beginning these procedures"
I was only half-paying attention and wound up selecting Use Passive FTP, and got a whole pile of -9002s. Un-checked this option and away the error went!
